* Because it self-anchors and is balanced by the countervailing barbs
, no knots are required
Feathers derive from a complex process of morphogenesis inside embryonic feather filaments that begins with the formation of barb
ridges and terminates with the formation of barbs
, free in plumulaceous feathers and regularly joined to a rachis in pennaceous feathers (Lucas & Stettenheim, 1972; Chuong & Widelitz, 1999; Prum & Dyck, 2003; Sawyer & Knapp, 2003).

Schmidt and his colleagues at the United States Department of Agriculture's Agricultural Research Service in Beltsville, Md., recently developed an instrument for stripping a feather's quill of its fibrous barbs
. It's a contraption much like a paper shredder but a "high-precision shredder," says Schmidt.
Schmidt and his team at the ARS developed an efficient method for sorting quill from barb
in chopped feather.
But Lochhead's structure is so awkward -- the putative revelations so contrived -- that one ends up irritated by the authorial gerrymandering rather than drawn into Barbs
' readily identifiable plight.
As seen in the movie's trailer released on Friday, Barbs
sets out on her own adventure such as joining a beauty pageant and transitioning into a man.
Even then, accidental contact with barbs
results in torn clothing and occasional minor injury.
It has been suggested rather that the injuries are a side effect of other benefits the males reap from the barbs
. Now, for the first time, we are able to show that this is the case," says Arnqvist.
fittings for connectors such as luers and tube-to-tube fittings are often selected through a trial and error process.
The lice hide between the barbs

One doesn't have to be a farm or ranch boy to know what barbed
